How is the direction of a stepper motor reversed?

  1. By reversing the polarity of the supply to the controller only
  2. By reversing the sequence of the pulses to the phases
  3. By swapping the rotor and stator
  4. By doubling the step rate
Show answer

Correct answer: By reversing the sequence of the pulses to the phases

The rotor follows the sequence of the phases, so the opposite sequence turns it the other way.
